RegExReplacer corrupts binary response need to be able to specify filter

[Andy Arismendi]

Hi, I ran into an issue where the response content type is application/zip and wasn't excluded due to the limited exclusion in the code linked below which caused corruption. It would be great to be able to specify a content type list to only apply the regex to e.g. text/html, application/json etc... in proxies.xml as an attribute for RegExReplacer.
